Since I'm often annoyed when my posts are downvoted without explanation, and I saw that this post was downvoted, I'll try to explain the downvotes.

Updating of values happens all the time; it's called operant conditioning. If my dog barks and immediately is poked with a hot poker, its value of barking is updated. This is a useful adaptation, as being poked with a hot poker decreases fitness. If my dog tries to mate and immediately receives an electric shock, its value of making is decreased. This is a harmful adaptation, as mating is a more fundamental fitness factor than electric shocks.

So, you seem to be explaining an observation that is not observed using a fact that is not true.
